[Vwdiesel] timing belt crank pulley torque

[mikitka]

I'm not up 100% on here but I have a 91 Jetta ECO diesel and my pulley did
come loose and yes it cost me a perfectly good brand new head and cam.

If you have the set up I'm thinking about with the twelve point bolt then
yes that is the torque but my Bentley went farther as to the point once you
set the torque to the 148 lbft then you have to turn the bolt half a turn
more. Now that was interesting because I had to block the crank with a piece
of wood between the crank journal and the block up inside the engine to keep
it from rotating. At least it is easy to take the oil pan off.

I am installing the timing belt crank pulley on a 1.6 td.  It is the 
crank style that has a notch in the end of the crank and a nub cast into 
the pulley as a key.  Two questions.  is this a JK or CY engine?  The 
engine has a hydraulic head and my Bentley doesn't cover the hydraulic 
head engines and I want to make sure the torque of 148 ft lbs with lubed 
threads is correct (14 mm bolt).  Is there a different procedure than 
what is in the Bentley manual?  I remember there has been some 
discussion about this style of pulley coming loose and ruining a 
perfectly good crank.
